Bolsonaro has been detained after authorities found he posed a concrete flight risk while under domestic detention.
The former head of state was found guilty of planning a armed takeover in last fall and sentenced more than 27 years in prison, but he was staying under confinement pending court reviews.
High Court Judge Alexandre de Moraes said the action to imprison the elderly politician was a precautionary step after "new facts" were revealed.
This encompassed seeking to disable his electronic bracelet and a call for a demonstration that could enable a chance to flee".
Court Filing Details Escape Concerns
In a paperwork permitting the custody, Justice Moraes said intelligence from the facility tracking the former president's confinement suggested the former leader's aim to disable the tracking monitor to ensure success in his getaway".
This, it said, would be made easier by the chaos caused by the protest called by his offspring.
His child, his son Flávio, who works as a senator, called for a assembly of his supporters near Bolsonaro's home to take place on the weekend.
His son wrote on online platforms on last Friday: "Are you going to fight for your country, or see it all from your phone there on your settee? I call on you to fight with us."
He said the demonstration would be so followers could "pray for his health and for the restoration of democratic rule in our country."
Embassy Asylum Concerns
Part of Justice Moraes's ruling was the potential of his move to foreign missions near the dwelling, considering that the inquiries revealed a history of organizing to seek refuge through a embassy office", a declaration said.
The judicial paperwork emphasizes that the American diplomatic mission in the national capital, the capital city, is positioned around 8 miles from the former president's residence.
International Reactions
Bolsonaro's legal woes have generated frustration from fellow populist conservative US President Trump, leading him to enact a half-rate duty on Brazilian product imports.
Bolsonaro is being detained in a federal law enforcement building in Brasilia and will have a detention review on Sunday.
Recent Legal Requests
It was only on Friday that the his legal team asked the High Court to allow him to complete his entire prison term under home confinement, with electronic monitoring.
They also petitioned that he be authorized to leave his home for medical care, saying he needed frequent medical attention for respiratory ailments and other ailments.
Details of Guilty Verdict
The former president was determined responsible of leading a scheme aimed at keeping him in power after he lost the national vote to his left-wing rival, Lula.
Supreme Court justices said that he was aware of a plot which encompassed plans to kill the current president and his running partner, Geraldo Alckmin, and to imprison and murder Justice Moraes - the top judicial official who has been presiding over the former president's case.
The plot was stopped because it failed to get the endorsement of the military leaders. His successor was took office without problem on 1 January 2023.
But a following week, on 8 January, many his backers stormed and vandalised government buildings in the federal district, the capital city.
The law enforcement took action and around fifteen hundred individuals were arrested.
The magistrates found that the protesters had been provoked by Bolsonaro whose strategy, they said, was for the country's army to intervene, bring back stability and return him to office.
At the time, Bolsonaro's lawyers called the decades-long sentence unreasonably severe".
He was also prohibited from campaigning for office until the year 2060 - a decade minus two years after the conclusion of his imprisonment.
The one-time head of state called the court case a political persecution and said it was designed to prevent him competing in the next presidential race.
